Data preservation and SAML Preserving SAML SSO-related settings can prevent the target instance from redirecting all authentication requests to the original IdP with the wrong issuer and audience parameters. To preserve SAML settings you will need to create data preservers for the following tables: System Property [sys_properties]: to preserve SAML properties. See Preserve SAML properties for instructions. X.509 Certificates [sys_certificate]: to preserve SAML certificates. User [sys_user]: to preserve SAML users. You also need to preserve properties, certificates, and users that are involved in SAML.
